Poles of a Magnet
The Law of Magnetism
- When two magnets are held close together, there will be an attractive or repulsive force between the magnets depending on how they are arranged:
Opposite poles attract; like poles repel
- The Law of Magnetism states that:
- Two like poles (S and S or N and N) repel each other
- Two unlike poles (S and N) attract each other
- The attraction or repulsion between two magnetic poles is an example of a non-contact force
